Florida-based Quality Boat Lifts is utilising Iglidur plain bearings from Igus on lifts used by both residential and commercial marinas and private owners to remove boats from the water.

The US company offers seven maintenance-free boat-lift devices, including the Alum-A-Vator and the industrial-grade Superlift.

Igus’s Iglidur P polymer bearings are used in the lifts’ direct-cable winding drive shafts, which raise and lower boats in and out of the water.

Each lift uses 10–20 Iglidur bearings. The bearings are designed to handle axial loads ranging from two to 30 tonnes.

Key benefits of product application

  • Unlike metal and bronze bushings, the Igus bearings do not corrode; this is thanks to their polymer design.
  • Iglidur P was chosen for its low moisture absorption, low wear rates and high load capacity.
  • The bearings are unaffected by the 450kg radial loads experienced during the operation of the boat lifts.
  • As the Iglidur bearings are lubrication free, they eliminate the need for maintenance.
  • The bearings are resistant to dirt, dust chemicals and ultraviolet rays.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
